That post is wrong. The issue is that the OP is using a CFW setup that doesn't support the type of XCI install that they did. Atmosphere with Sig Patches supports all. The issue is one of Kosmos, as it always is. It does not have full FS patching.
I love that other people help and encourage it. I just want people to post things that are correct.
If you have a problem with what people post, might as well get off temp, seem like you get pissed off easily, go ahead call yourself "Mr I know the answers to all your questions".
